Unfortunately, I can't add anything constructive regarding how to extricate yourself from your particular predicament. However, the subject/events/action which brought you into this makes my skin creep a bit: My neighbour's parents went into a care home and he (the neighbour) objected to the fact that they were being given Valium and insisted this or anything similar be stopped. The result was that he, his wife, their sons, his wife's mother and sister, and others connected to him were all banned from visiting his parents. A court case resulted, he really struggled to find useful representation and ended up representing himself. The final outcome was that through the court he was gagged, forbidden to discuss any of the details of the case - forever. During all of this (three years in total) his father died but once the case was over his mother was moved to another home (the only good outcome) where they all got to visit her until she died within 5 months. Social Services and the care homes regulator/watchdog all became involved. I imagine they would sue me for libel if I said they variously colluded with the care home and/or turned a blind eye.
Care homes (at least in the UK) are dangerous processing stations and there is no way I will risk being put in one as an inmate.
I wish you luck.
